KMM High-Precision Non-Contact Displacement Sensors for Extreme Environments

KMM Precision Measuring has introduced high-precision displacement sensors that measure the movement of conductive components without physical contact. Designed for extreme environments, these sensors operate in temperatures from –320°F to 1000°F (short-term up to 1200°F) and pressures up to 5000 psi, making them ideal for rocket engines, nuclear systems, and high-temperature testing.

Key Specifications

• Temperature range: –320°F to 1000°F continuous, short-term up to 1200°F
• Pressure capability: up to 5000 psi (KD-1925 model), up to 3500 psi (KD-1950 and KD-1975)
• Measurement principle: Non-contact sensing of conductive surfaces
• Construction: Hermetically sealed, laser-welded Inconel housings
• Cables: Metal-jacketed, mineral-insulated for extreme durability
• Signal conditioning: KDM-8206 electronics
• Available systems: Single-channel NEMA enclosure, bench-top, or rack-mountable Eurocard (up to 12 channels)

Originally developed for NASA and the nuclear power industry, the sensors withstand high heat, pressure, vibration, and contaminants where conventional contact sensors would fail.

Target Applications

• Aerospace propulsion and rocket engine turbopumps
• Nuclear power systems
• High-temperature materials research
• Power generation equipment testing
• Extreme environment laboratory setups

The non-contact design enables reliable measurement of component movement in conditions where physical contact is impossible or unsafe.
